AN-G/2i type intelligent gateway

I. Project Background and Core Challenges

A smart park is a complex complex that encompasses nume≈rous scenarios such as office buildings, factories, ☆parking lots, public facilities, and energy stations. Its intelligent constructionΩ requires the deployment of a vast number of sensing devices to $monitor various states:

Energy metering: Water, electricity and gas meters for each floor and tenant.

Environmental monitoring: Temperature and humidity, air quality (PM2.5, CO₂), illuminance sensors.

Facility monitoring: The operating status of water pumps, fans, and lighting circui★ts.

Security and fire protection: door magnets, alarm devices, fire hydrant pressure sensor₹s, etc.

These application scenarios bring unique challenges:

1. Scattered and sparse points: Hundreds or even thousands of sensors/instruments are scattered throughout the park, with usuaπlly only 1-2 devices at each point, but the total number is huge.$ The wiring cost of the traditional centralized collection solution is extremely high.

2. Extremely high access cost pressure: If each decentralized point adopts a high-performance gateway, the total cost will be uncont≥rollable. The project requires a cost-effective access solution↔ that can "integrate fragmented parts into a whole".

3. Stringent real-time requirements: The management platform of the park (such as the IOC intelligent operation® Center) needs to respond quickly to abnormal situations. For instance, a fire alar↕m signal must be uploaded immediately instead of waiting for the scheduled coll↑ection cycle 15 minutes later. The traditional periodic collec£tion mode cannot meet such real-time alarm requirements.

Ii. Precise Positioning and Solutions for the AN-G/2i Intelligent Gateway

The product definition of the AN-G/2i intelligent gateway precisely targets the above€-mentioned pain points. It does not pursue ultimate performance and multi-protocol complexity, b∏ut focuses on economy, flexibility and real-time performance. It is an λideal convergence point for the massive "nerve endings" data of smart parks.

1. Economically flexible distributed deployment (addressing the issues≠ of scattered locations and high costs)

Precise product positioning: As a compact and cost-effective gateway, the AN-G/2i can be widely deployed¶ in regional weak current Wells and distribution boxes, ¥specifically responsible for collecting data from several to a dozen sensors ±in a small surrounding area.

Flexible communication methods: It usually has 4G Cat.1 or wireless Internet access functions. For‌ scattered points where it is difficult to lay optical₹ fibers, data can be directly uploaded to the cloud platform through the operatorδ's wireless network, completely solving the "last mile" wiring problem and greatly reduci₽ng implementation costs and construction periods.

The value of "edge aggregation" : The vast majority of gateways adopt "polling" data collection, reading and uploading da£ta at fixed intervals (such as 5 minutes). This means that the're will be an average delay of 2.5 minutes from th©e occurrence of an alarm signal to its detection by the system, which cannot meet the requirements£ of real-time monitoring.

The solution of AN-G/2i: It provides the "Change reporting" or "active reportiγng" mode.

Working principle: Under the condition that most data remains unchanged (such as the electricity meter not s✔kipping words every second), the change reporting mechanism greatly reduces invalid data transmissi♠on, saves network traffic, which is particularly important for scenarios wher€e 4G is charged based on data traffic, and also red uces the power consumption of the gateway.

Iii. Description of Typical Application Case Scenarios

Case: Environmental and energy Monitoring Project of a certain smart technology park

Project Overview: The park needs to conduct meticulous monitoring and management of the indoor and outdoor environm‌ental quality of 10 buildings and the electricity consumption of each unit. More than 500 t↑emperature, humidity and CO₂ sensors and 200 smart electricity meterσs need to be connected to the IOC platform of the park.

Implementation process

1. Decentralized deployment: Deploy one AN-G/2i gateway in the weak current room on each fl±oor, which is responsible for connecting 8-10 environmenta<l sensors and 5-8 electricity meters on this floor (connected hand i n hand via the RS-485 bus).

2. Wireless networking: The gateway uploids data to the park's cloud platform via the existing Wi-Fi in the buil∏ding or by deploying a 4G Cat.1 module.

3. Function Configuration

Configure a periodic report once an hour for all electricity meters for energy δconsumption statistics and billing.

Enable the change reporting function for all environmental sensors, with the threshold set a✘s follows: immediately report when the temperature changes by ±1℃, when the humidi≥ty changes by ±5%, and when the CO₂ concentration exceeds 1000ppm.

Project achievements

Cost control: The solution of adopting multiple low-cost G/2i gateways reduces the tota₽l cost by more than 40% compared to using a small number of high-performa<nce gateways and laying a large number of communicati₽on cables.

Ultimate experience: Park managers can view the environmental situation of the entire park in real time on the IOC la&rge screen. When the CO₂ concentration in a meeting room rises due to a ∑meeting, the platform immediately receives the data and automatically triggers t∞he fresh air system to increase the wind speed, enhancing the office experience.

Efficient operation and maintenance: When a water pipe leaks at a certain location, causing an abnormal increase in humidity, the alarφm information is pushed to the mobile phones of th♦e operation and maintenance personnel within seconds, achieving rapid location and hand<ling, and avoiding greater losses.

The AN-G/2i type intelligent gateway of Ailuo Technology plays AN indispensable "capil£lary" role in the smart park project. It does not aim for a "big and compreh"ensive" functionality. Instead, through precise product positioning and an innovative ch≠ange reporting mechanism, it perfectly addresses the two c$ore pain points of the massive and scattered sensor access₩ in smart parks: economy and real-time performance.

It significantly lowers the deployment threshold and cost of the Internet of Things through flexibδle deployment and wireless connection.

It adopts a dual mode of change reporting and periodic reporting, wh®ich not only ensures the real-time nature of data but also guarantees the stability of t♦he system, transforming the management of the park fr↓om "passive query" to "active perception", truly achieving intelligent ×and efficient operation.

This product is a powerful tool in the product line of Ai luo Technology for "fragmented, low-power, and strong£ real-time" Internet of Things applications, and it is an ideal choice for building αthe nerve endings network of smart cities.
